The invention relates to a high-precision RV speed
reducer comprehensive testing device, which comprises a base, a first sliding platform, a second sliding platform, a first motor, a first
torque sensor, a second motor, a second
torque sensor, a first angle sensor, an input shaft bracket and an output shaft bracket. Compared with the prior art, the high-precision RV speed
reducer comprehensive testing device designs the sliding platform
assembly capable of being rapidly disassembled and assembled, so that the assembling and disassembling process of an to-be-tested RV speed
reducer is more convenient and faster; the output shaft bracket and the input shaft bracket can be used for adapting to the requirements of sensors with different specifications; the limiting parts of the sliding platforms improve the test precision; the double-measuring-range torque sensors can adapt to measurement of speed reducers of different series models, and can also realize test of transmission precision under
light load; an input shaft of the to-be-tested RV speed reducer is installed in two bearing inner rings sharing the same
horizontal axis, thereby facilitating the adjustment of a bearing clearance;and the double-reading-head circular
grating angle sensors meet the requirement that the transmission precision is tested in a high-speed state.
